Fig. 36

Diagnosis

By the structure of the endogyne, Z. feti sp. nov. resembles Z. maracandica but differs by the extended median receptacles, which are considerably longer than the lateral pair (vs similarly long in the latter species, cf. Figs 36 D–E, 38E–I).

Etymology

The specific epithet is given after our good friend and colleague Victor Fet (Marshall University, USA), the author of many works devoted to the spiders of Turkmenistan.
